United States Patent 3,295,595 HEAT TRANSFER APPARATUS William H.Armstrong, 197 Sandwich St., Plymouth, Mass. 02360 Filed July 29, 1964,Ser. No. 385,978 7 Claims. (Cl. 165-56) This invention relates to heattransfer apparatus.

One object of my invention is to provide heat transfer 1 apparatus whichis adaptable for use with stock panels commonly used to assembleceilings.

Another object is to provide such apparatus that may can be manufacturedeconomically and in large quantities and is so constructed that it takesfinal form, ready for use, by a simple production operation.

The foregoing and other objects which will appear as the nature of theinvention is better understood, may be accomplished by a combination andarrangement such as is disclosed by the drawing. The nature of theinvention is such as to render it susceptible to various changes andmodifications, and therefore, I am not to be limited to the constructiondisclosed by the drawing, nor to the particular parts described in thespecification; but am entitled to all such changes therefrom as fallwithin the scope of my claims.

In the drawing:

FIG. 1 is a perspective view of my heat transfer apparatus assembledwith two ceiling panels and a heating conduit.

FIG. 2 is an enlarged, end elevational view of the assembly shown inFIG. 1.

FIG. 3 is a fragmentary, end elevational view of the assembly shown insaid FIG. 2, as installed in a building, the panels being shown insection.

FIG. 4 is a fragmentary, perspective view of the two sections forming myapparatus assembled around a conduit, the panels being omitted.

As illustrated, my heat transfer apparatus has two heat transfersections 12 and 14 which are of duplicate construction. Each section hasa contact holder portion 16 and 16a which, as shown, are arcuate inshape. Below each said holder portion is a joiner portion 18 and 18awhich are shown extending slightly diagonally outward, and each has ahole 20 and 20:; respectively to receive n'vets 30 later described.

Bead receiving portions 22 and 22a extend laterally outward from one endof said joiner'portions, and extending from the opposite end of thelatter are connector portions 24 and 24a that terminate in diagonalportions 26 and 26a as shown. From the latter flat contact portions 28and 28a extend angularly, which terminate my apparatus.

Said sections 12 and 14 are used together, as shown in said FIGS. 1 and3, with two of said contact holder pertions 16 and 16a in contact withand partly extending around a temperature modifying member. The latteris shown as a conduit C such as a well-known length of pipe throughwhich hot water or steam, or a cooling medium may circulate, dependingupon whether a heating or cooling efiect is desired.

Beyond said conduit C said joiner portions 18 and 18a are preferablyconnected by pin members 30 shown as rivets, thus firmly keeping saidholder portions 16 and "ice 16a in contact with said conduit C. Said pinmembers each extend through holes 20 and 20a as shown, and are spacedapart. They are put in place during an installation of my apparatusafter said conduit C and bolder portions 16 and 16a are in assembledposition in contact with said conduit C.

My apparatus is shown held in position by hangers 32 that extend throughslots 33 in said joiner portions 18 and 18a and are attached to a beam Bas by a hook portion 0 or by welding, or flat straps may be used.

My apparatus is used in combination with well-known metal pans or panels34 having angular sides as shown. Each side has an outer extremityportion 36, adjoining which is a beaded portion 38 extending inwardly.Next to the latter is a connecting portion 40 that is beveled as at 42where it joins the main face or flat surface 44 of the panel.

In use, opposed sides 34 of two different panels adjoin each other.Inwardly of and next to each of said adjoining sides are said twosections 12 and 14 of my apparatus, the holder portions 16 and 16a ofwhich extend partly around and in contact with said conduit C which isabove said panel sides 34. Said joiner portions 18 and 18a are justbeyond said panel sides 34 and are fastened together by said pin members30 as above explained. The beaded portions 38 of the panel sides extendinto said outwardly extending portions 22 and 22a while said connectorportions 24 and 24a are in contact with said panel connecting portions40. Said contact portions 28 and 28a are parallel with and flat againstsaid panel main face 44, hence heat from said conduits C, by conduction,next passes to said heat transfer sections 12 and 14 and finally fromsaid contact portions 28 and 28a to the panel face portions 44.

What I claim is:

1. Heat transfer apparatus in combination with two panels, said panelseach having a face portion and a side extending angularly therefrom,said sides respectively adjoining each other and each said sideembodying an inwardly extending head portion spaced respectively fromsaid face portions, said apparatus embodying heat transfer means havingtwo holder portions extending beyond said panel sides, two laterallyoutward extending bead receiving portions inwardly of said panel sides,said panel bead portions extending respectively into said bead receivingportions, and two contact portions extending angularly relative to saidbead receiving portions and respectively contacting said face portions.

2. Heat transfer apparatus in combination with two panels as set forthin claim 1 in which said panels each has an outer extremity portionadjoining a said panel bead portion, and said heat transfer sectionseach has a joiner portion, parts of which are respectively laterallyopposite said outer extremity portions.

3. Heat transfer apparatus in combination with two panels as set forthin claim 2 in which said panels each has an outer extremity portionadjoining a said panel bead portion, and said heat transfer sectionseach has a joiner portion, parts of which are respectively laterallyopposite said outer extremity portions, and means connecting said joinerportions at a point beyond a said panel side.

4. Heat transfer apparatus in combination with two panels as set forthin claim 2 in which said panels each have a connecting portion extendingrespectively from said panel bead portions and said sections each have aconnector portion extending from said bead receiving portion and arerespectively opposite said panel connecting portions.

5. Heat transfer apparatus in combination with two panels, said panelseach having a face portion and a side extending angularly therefrom,said sides respectively adjoining each other and each said sideembodying an extremity portion, a beaded portion adjoining the latterand extending inwardly therefrom, and a connecting portion adjoiningsaid beaded portion and connected to said face portion, said apparatusembodying heat transfer means having two holder portions extendingbeyond said panel sides, two joiner portions extending from said holderportions and extending inwardly of and parallel With said panel outerextremity portions, two laterally outward extending bead receivingportions extending from said joiner portions and being inwardly of saidpanel sides, said panel bead portions extending respectively into saidhead receiving portions, two connector portions extending from said beadreceiving portions and extending inwardly of and being respectivelyopposite to and parallel with said panel connecting portions, and twocontact portions extending angularly relative to said connector portionsof said means and being respectively parallel with and in contact withsaid panel face portions.

6. A heat transfer member for use with two panels each having a faceportion and a side extending angularly thereform, said sides adjoiningeach other and each embodying an inwardly extending head portion spacedrespectively from said face portions, said heat transfer memhercomprising two holder portions to extend beyondv said panel sides, twolaterally extending bead receiving portions to extend inwardly of saidpanel sides to receive said panel bead portions, two connector portionsextending downwardly from said latter portions and two contact portionsextending angularly relative to said connector portions to thereby makecontact with said panel face portions.

7. A heat transfer member as set forth in claim 6, in which saidconnector portions extend downwardly from said bead receiving portionsand thence diagonally outward until they reach said contact portions,said contact portions extending horizontally.
